顺层岩质滑坡多级溃屈机理研究

he landslide located at the upper reaches of the hydropower station is a large-scale consequent rock landslide. Making a systematic analysis and study on this landslide based on the data of the regional geological surveys, large scale topographical map, drilling, cavern as well as on-site inspection, it reveal that the landslide has the typical characteristics of the local rock turned upwards, the scarp after the landslide and the bending damage with several times. With the viewpoint of the dynamical evolution, using the methods of physical model test, the formation mechanism and evolution process are analyzed: Under the combined power effects of inside(Tectonic activity) and outside(River erosion),the landslide begain to slide along with the weak layers, it is a typically bed-burst landslide. There is a destruction by the way of several times' bed-burst at the same time. The physical model test is established to test and verify the whole process of destruction of consequent rock landslide. After Understanding the formation mechanism and evolution process of the landslide, it is probably to forecast the future evolution trend of the landslide to combine the geological environment around the landslide, and compute the Landslide's stability.
